Item 5.02
Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On May 1, 2026, Theodora (“Doretta”) Mistras informed Viatris Inc. (the “Company”) that she would voluntarily cease to serve as Chief Financial Officer to pursue another professional opportunity. Ms. Mistras will cease to serve as Chief Financial Officer effective May 8, 2026 and will remain employed by the Company until May 22, 2026 for transition purposes. Ms. Mistras’ resignation was not related to any disagreement between Ms. Mistras and the Company on any matter relating to the Company’s accounting practices, financial statements, internal controls, or operations.
On May 4, 2026, the Board of Directors of the Company (the “Board”) appointed Paul Campbell, Viatris’ current Chief Accounting Officer and Corporate Controller, to also serve as interim Chief Financial Officer of the Company, effective May 8, 2026, until a permanent Chief Financial Officer is appointed by the Board. Mr. Campbell, age 59, has served as Viatris’ Chief Accounting Officer and Corporate Controller since the closing of the combination of Mylan N.V. (“Mylan”) with Pfizer's Upjohn business (the “Combination”) on November 16, 2020. As Chief Accounting Officer and Corporate Controller, he is responsible for oversight of the day-to-day operations of the accounting and finance functions of the Company, including planning, implementing, and managing the Company’s finance and accounting activities. Prior to the closing of the Combination, Mr. Campbell served as Mylan’s Chief Accounting Officer, Senior Vice President and Controller. Before his appointment as Chief Accounting Officer in November 2015, Mr. Campbell served as Mylan’s Senior Vice President and Controller beginning in May 2015, with responsibility for overseeing the company’s accounting and financial operations and reporting, and he previously held roles of increasing responsibility at Mylan since 2002.
There are no arrangements or understandings between Mr. Campbell and any other persons pursuant to which he was selected as interim Chief Financial Officer, he has no family relationships with any of the Company’s directors or executive officers and he has no direct or indirect material interest in any transaction requiring disclosure under Item 404(a) of Regulation S-K.

Ms. Mistras will not be eligible for severance or equity vesting in connection with her departure.  She is eligible to receive a pro rata bonus for the portion of 2026 for which she served as an employee (based on actual Company performance but not to exceed target) and will be required to provide a release of claims and comply with customary restrictive covenants.
Item 7.01
Regulation FD Disclosure.
